     25WHAT'S NEW
     26==========
     27
     28Release 2.8.3:
     29
     301. Fix for handling SOS.
     31
     32Release 2.8.2:
     33
     341. Fixed recognition of Glpk source in main configure.
     35
     362. Minor bugfixes in CoinUtils, Clp, and Cbc.
     37
     38Release 2.8.1:
     39
     40   Ted, please fill this in!
     41
     42Release 2.8.0:
     43
     441. Introduced new secondaryStatus 8 to indicate that solving stopped due to an iteration limit.
     45
     462. Solution pool is now accessible via the command line and the CbcMain* interface.
     47
     483. New mipstart option to read an initial feasible solution from a file. Only values for discrete
     49   variables need to be provided.
     50
     514. Added Proximity Search heuristic by Fischetti and Monaci (off by default):
     52   The simplest way to switch it on using stand-alone version is "-proximity on".
     53
     54   Proximity Search is the new "No-Neighborhood Search" 0-1 MIP refinement heuristic recently proposed by
     55   Fischetti and Monaci (2012). The idea is to define a sub-MIP without additional constraints but with a
     56   modified objective function intended to attract the search in the proximity of the incumbent. The approach
     57   works well for 0-1 MIPs whose solution landscape is not too irregular (meaning the there is reasonable
     58   probability of finding an improved solution by flipping a small number of binary variables), in particular
     59   when it is applied to the first heuristic solutions found at the root node.
     60   
     615. An implementation of Zero-Half-Cuts by Alberto Caprara is now available.
     62   By default, these cuts are off.  To use add to your command line -zerohalfCuts root (or other options) or just -zero.
     63   So far, they may help only on a small subset of problems and may need some tuning.
     64
     65   The implementation of these cuts is described in
     66   G. Andreello, A. Caprara, and M. Fischetti
     67   "Embedding Cuts in a Branch and Cut Framework: a Computational Study with {0,1/2}-Cuts"
     68   INFORMS Journal on Computing 19(2), 229-238, 2007
     69   http://dx.doi.org/10.1287/ijoc.1050.0162
     70
     716. An alternative implementation of a reduce and split cut generator by Giacomo Nannicini is now available.
     72   By default, these cuts are off.  To use add to your command line -reduce2AndSplitCuts root (or other options).
     73
     74   The implementation of these cuts is described in
     75   G. Cornuejols and G. Nannicini
     76   "Practical strategies for generating rank-1 split cuts in mixed-integer linear programming"
     77   Mathematical Programming Computation 3(4), 281-318, 2011
     78   http://dx.doi.org/10.1007/s12532-011-0028-6
     79
     807. An alternative robust implementation of a Gomory cut generator by Giacomo Nannicini is now available.
     81   By default, these cuts are off.  To use add to your command line -GMI root (or other options).
     82
     83   The implementation of these cuts is described in
     84   G. Cornuejols, F. Margot, and G. Nannicini
     85   "On the safety of Gomory cut generators"
     86   http://faculty.sutd.edu.sg/~nannicini/index.php?page=publications
     87
     888. To encourage the use of some of the more exotic/expensive cut generators a parameter -slowcutpasses has been added.
     89   The idea is that the code does these cuts just a few times - less than the more usual cuts.  The default is 10.
     90   The cut generators identified by "may be slow" at present are just Lift and project and ReduceAndSplit (both versions).
     91   
     929. Allow initialization of random seed by user.  Pseudo-random numbers are used in Cbc and Clp.  In Clp they
     93   are used to break ties in degenerate problems, while in Cbc heuristics such as the Feasibility Pump use them   
     94   to decide whether to round up or down.  So if a different pseudo-random seed is given to Clp then you may get
     95   a different continuous optimum and so different cuts and heuristic solutions. This can be switched on by
     96   setting randomSeed for Clp and/or randomCbcSeed for Cbc.  The special value of 0 tells code to use time of day
     97   for initial seed.
     98   
     9910. Building on this idea, Andrea Lodi, Matteo Fischetti, Michele Monaci, Domenico Salvagnin, Yuji Shinano, and Andrea Tramontani
     100   suggest that this idea be improved by running at the root node with multiple copies of solver, each
     101   with its own different seed and then passing in the solutions and cuts so that the main solver has a richer
     102   set of solutions and possibly stronger cuts.  This is switched on by setting -multipleRootPasses.  These can also
     103   be done in parallel.
     104 
     10511. Few changes to presolve for special variables and badly scaled problems (in CoinUtils).
     106
     10712. New option -extraVariables <number> which switches on a trivial re-formulation that introduces extra integer variables
     108    to group together variables with same cost.
     109
     11013. For some problems, cut generators and general branching work better if the problem would be infeasible if the cost is too high.
     111    If the new option -constraintFromCutoff is set, the objective function is added as a constraint which rhs is set to the current
     112    cutoff value (objective value of best known solution).
     113

    112 
    113    * Introduced new secondaryStatus 8 to indicate that solving stopped due to
    114      an iteration limit.
    115    * Solution pool is now accessible via the command line and the CbcMain*
    116      interface.
    117    * New mipstart option to read an initial feasible solution from a file.
    118      Only values for discrete variables need to be provided.
    119 
    120    * Added Proximity Search heuristic by Fischetti and Monaci (off by
    121      default): The simplest way to switch it on using stand-alone version is
    122      ```-proximity on```.
    123 
    124      Proximity Search is the new "No-Neighborhood Search" 0-1 MIP refinement
    125      heuristic recently proposed by Fischetti and Monaci (2012). The idea is
    126      to define a sub-MIP without additional constraints but with a modified
    127      objective function intended to attract the search in the proximity of the
    128      incumbent. The approach works well for 0-1 MIPs whose solution landscape
    129      is not too irregular (meaning the there is reasonable probability of
    130      finding an improved solution by flipping a small number of binary
    131      variables), in particular when it is applied to the first heuristic
    132      solutions found at the root node.
    133    
    134    * An implementation of Zero-Half-Cuts by Alberto Caprara is now available.
    135      By default, these cuts are off. To use add to your command line
    136      -zerohalfCuts root (or other options) or just -zero. So far, they may
    137      help only on a small subset of problems and may need some tuning.
    138 
    139      The implementation of these cuts is described in G. Andreello, A.
    140      Caprara, and M. Fischetti "Embedding Cuts in a Branch and Cut Framework:
    141      a Computational Study with {0,1/2}-Cuts" INFORMS Journal on Computing
    142      19(2), 229-238, 2007 http://dx.doi.org/10.1287/ijoc.1050.0162
    143 
    144    * An alternative implementation of a reduce and split cut generator by
    145      Giacomo Nannicini is now available. By default, these cuts are off. To
    146      use add to your command line -reduce2AndSplitCuts root (or other
    147      options).
    148 
    149      The implementation of these cuts is described in G. Cornuejols and G.
    150      Nannicini "Practical strategies for generating rank-1 split cuts in
    151      mixed-integer linear programming" Mathematical Programming Computation
    152      3(4), 281-318, 2011 http://dx.doi.org/10.1007/s12532-011-0028-6
    153 
    154    * An alternative robust implementation of a Gomory cut generator by Giacomo
    155      Nannicini is now available. By default, these cuts are off. To use add to
    156      your command line -GMI root (or other options).
    157 
    158      The implementation of these cuts is described in G. Cornuejols, F.
    159      Margot, and G. Nannicini "On the safety of Gomory cut generators"
    160      http://faculty.sutd.edu.sg/~nannicini/index.php?page=publications
    161 
    162    * To encourage the use of some of the more exotic/expensive cut generators
    163      a parameter -slowcutpasses has been added. The idea is that the code does
    164      these cuts just a few times - less than the more usual cuts. The default
    165      is 10. The cut generators identified by "may be slow" at present are just
    166      Lift and project and ReduceAndSplit (both versions).
    167    
    168    * Allow initialization of random seed by user. Pseudo-random numbers are
    169      used in Cbc and Clp. In Clp they are used to break ties in degenerate
    170      problems, while in Cbc heuristics such as the Feasibility Pump use them
    171      to decide whether to round up or down. So if a different pseudo-random
    172      seed is given to Clp then you may get a different continuous optimum and
    173      so different cuts and heuristic solutions. This can be switched on by
    174      setting randomSeed for Clp and/or randomCbcSeed for Cbc. The special
    175      value of 0 tells code to use time of day for initial seed.
    176    
    177    * Building on this idea, Andrea Lodi, Matteo Fischetti, Michele Monaci,
    178      Domenico Salvagnin, Yuji Shinano, and Andrea Tramontani suggest that this
    179      idea be improved by running at the root node with multiple copies of
    180      solver, each with its own different seed and then passing in the
    181      solutions and cuts so that the main solver has a richer set of solutions
    182      and possibly stronger cuts. This is switched on by setting
    183      -multipleRootPasses. These can also be done in parallel.
    184  
    185    * Few changes to presolve for special variables and badly scaled problems
    186      (in CoinUtils).
    187 
    188    * New option -extraVariables <number> which switches on a trivial
    189     re-formulation that introduces extra integer variables to group together
    190     variables with same cost.
    191 
    192    * For some problems, cut generators and general branching work better if
    193      the problem would be infeasible if the cost is too high. If the new
    194      option -constraintFromCutoff is set, the objective function is added as a
    195      constraint which rhs is set to the current cutoff value (objective value
    196      of best known solution).
    197 
    198  * Release 2.7.8:
    199 
    200    * Change message when LP simplex iteration limit is hit from "Exiting on
    201      maximum nodes" to "Exiting on maximum number of iterations"
    202    * Fix for using overlapping SOS.
    203    * Fixes in buildsystem.
    204 
    205  * Release 2.7.7:
    206 
    207    * Fix to report interruption on user event if SIGINT is received by
    208      CbcSolver. model->status() should now be 5 if this event happened. Added
    209      method CbcModel::sayEventHappened() to make cbc stop due to an 'user
    210      event'.
    211 
    212    * Other minor fixes.
